Hamster Food
It is important that the hamster food you give your hamster is varied and fresh (that is to say do not give stale hamster food and replace old food in the cage regularly).
Basic hamster food should include the dried hamster food you get from pet shops and your hammy will probably eat about a desert spoonful a day, but leave enough in his food bowl so he does not go hungry. You may find your hamster will not eat everything in the hamster food mix, or that they prefer one make over another; they are just choosy like that!
Your hamster will probably also like seeds, particularly sunflower seeds, peanuts, dried fruit and vegetables (apple and carrot seem to be popular), but you will need to try different things to see which go down well, and which are rejected.
You can supplement the dried hamster food with fresh vegetables; carrots, cucumber, courgette, but not potato. You can get special carrot holders that hang on the bars of the cage and will hold a carrot for the hamster to eat, or alternatively cut up pieces and place in the food bowl. Hamsters also do not usually like citrus fruit (lemons etc) and tomatoes. Fresh dandelion leaves are usually also very popular with hamsters, but make sure they have not been treated with weed killer.
In addition, make sure there is always a supply of fresh water in the cage to supplement the hamster food.
